Why in News

  • On International Sickle Cell Day 2026, the President reaffirmed India's target to eliminate sickle cell anaemia before 2047.
  • This goal operates under the National Sickle Cell Anaemia Elimination Mission.
  • The President marked this commemoration at Omkareshwar, Madhya Pradesh, celebrating a significant health milestone.

Background and Observance

  • The world observes International Sickle Cell Day every year on 19th June to raise awareness about the disease.
  • This day promotes early diagnosis, proper treatment, and effective prevention of sickle cell disease.
  • The United Nations General Assembly officially recognized this day through a resolution adopted on 22nd December 2008.
  • The resolution described sickle cell disease as a major public health problem and a vital global genetic disease.
  • The theme for 2026 is Closing the Survival Gap: Equity in Sickle Cell Disease.
  • This theme emphasizes bridging existing disparities and uniting local and global communities to support patients.

Understanding Sickle Cell Disorder

  • Sickle Cell Disease is a group of inherited, chronic blood disorders affecting the body.
  • It alters the structure of hemoglobin, which is the vital protein inside red blood cells that carries oxygen.
  • Instead of remaining flexible and round, affected red blood cells mutate into rigid, crescent, or sickle shapes.
  • It is caused by a structural mutation in the HBB gene, which gives instructions for making beta-globin.
  • The disease follows an autosomal recessive inheritance pattern.
  • A person develops the disease only if they inherit two abnormal hemoglobin genes from both parents.
  • Individuals inheriting only one mutated gene copy are called carriers or possess the Sickle Cell Trait.
  • Carriers generally live healthy lives without symptoms but can pass the mutated gene to their biological children.

Health Impact and Pathophysiology

  • Abnormal red blood cells become rigid and sticky, reducing their ability to flow smoothly through blood vessels.
  • This leads to blocked circulation and a severe disruption in oxygen supply throughout the body.
  • Vaso-occlusive crises happen when sickle cells block small blood vessels, causing intense pain and tissue damage.
  • Rapid destruction of sickle cells results in chronic anaemia, persistent fatigue, breathlessness, and weakness.
  • Repeated spleen injury reduces overall immunity, making patients vulnerable to serious infections.
  • Long-term oxygen deprivation causes progressive damage to the brain, lungs, kidneys, and other vital organs.
  • Symptoms usually appear around 5 to 6 months of age as fetal hemoglobin levels decline.

India's National Efforts

  • The National Sickle Cell Anaemia Elimination Mission launched in 2023 to address the heavy disease burden.
  • The mission specifically targets tribal populations and aims for total elimination by 2047.
  • The government implements this mission under the National Health Mission across 17 high-focus states.
  • It focuses heavily on early detection, proper treatment, public awareness, and disease prevention.
  • The mission adopts a mission-mode approach combining large-scale screening and community awareness.
  • It targets approximately 7 crore people aged 0 to 40 years over a span of three years from 2023 to 2026.
  • The Ministry of Health and Family Welfare and the Ministry of Tribal Affairs jointly implement this mission.

Treatment and Management

  • Pain management uses analgesics, anti-inflammatory drugs, and proper hydration to control severe crises.
  • Hydroxyurea therapy increases fetal hemoglobin production to reduce cell sickling and pain episodes.
  • Regular antibiotics and vaccination prevent severe infections, particularly in infants and young children.
  • Doctors use blood transfusions to reduce dangerous complications such as stroke and severe anaemia.

Prelims in Focus

  • International Sickle Cell Day falls annually on 19th June.
  • The United Nations General Assembly recognized the day in 2008.
  • The HBB gene mutation causes this hereditary blood disorder.
  • The national mission targets 7 crore people across 17 high-focus states.
  • The target year for complete elimination in India is 2047.
